I'm also stock rom/kernel, rooted and have cwm recovery, supersu, and voodoo ota rootkeeper. I told ota rootkeeper to backup root. I copied the update file to the N7 and ran the update through cwm recovery. After the update I kept root and kept cwm recovery by answering Yes to a prompt about disabling flashing stock recovery (thus keeping cwm recovery) and Yes to a prompt about recovering root. Very easy overall.

Hi to copy the update.zip you used adb or just wired to PC and copied it in the -root of sd?
If i install the update downloaded by the nexus and then run rootkeeper would be good or better install it through recovery?
Really thanks

I downloaded the update (6ece895ecb23.signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip) to my computer and from there to the N7 via usb cable. That way I could easily check the md5 checksum and I don't always trust d/l straight to the N7 although it should work fine. You can even install the zip from the download folder.
Do you have root via Superuser or Supersu? With Supersu and ota rootkeeper (told it to backup root) I kept both root and my cwm recovery. Without them, the update will flash the stock recovery overwriting a custom recovery like cwm or twrp and you will loose root. Even so, you can re-root after getting 4.2.2 and you can install a custom recovery.
I'm not sure if Superuser or twrp recovery gives the same results as I had, but the setup I posted above works beautifully. You do need to backup root with rootkeeper before flashing the update.

i lost root after updating even with rootkeeper. i simply flashed the supersu file i already had on my sd and all is fine

R: Help for updating
I have supersu and i ve configured rootkeeper when just installed means i checked everything
So now if i download the update for nakasig and install it through cwm and then put super su.apk in root of SD and then open rootkeeper and restore root will work?

4.3 OTA Update Failed - Bad debuggerd file

Trying to do the 4.3 OTA update. It fails with the message indicating that /system/bin/debuggerd does not have the expected entries.
Looks like Stickmount probably corrupted the file.
Could someone please post an original /system/bin/debuggerd file from Nexus 10 for version 4.2.2 / JDQ39?
It would be greatly appreciated.
Thanks a lot in advance.

I searched all over for this damn file and only ever found one for the N7 which didn't work. Extracted this one from the N10 4.2.2 factory image and successfully updated.

Hopefully this link works, otherwise PM me.

Thank you so much!!!
It worked perfectly!
I dropped the file in place with Root Explorer in ES File Manager.
Then used TWRP adb sideload to apply the OTA update file.
Then I used Goo Manager to reinstall TWRP recovery.
Then used TWRP adb sideload to apply the SuperSU 1.51 zip file to restore root.
All is good.....Thanks again

I just ran the normal OTA update, then used CF-Autoroot, which also worked fine for anyone wondering (It has been updated for 1.51).

There is no SU binary installed, and SuperSU cannot install it

Greetings Folks!!!
I am on CM12.1 Lollipop 5.1.1 Nightly, and ROOT access was working fine on my phone so far. When I launched Thunderzap today, I noticed that the app was waiting on "Requesting ROOT Privileges" for over 2 mins, and also the SuperSU app was missing from the app drawer. Thunderzap had been recently updated, and I suspect that might have triggered the root access to be requested again, but it wasn't given root access for some reason, and I never got a prompt to grant it root access. However, my other apps like ROOT Explorer, Shell Terminal Emulator etc, which weren't updated off lately, worked fine with root access. Not sure why now, but I thought reinstalling SuperSU-v2.46 might be a good idea at that time, and I flashed that file. And ever since I have completely lost my root access. When I launch the SuperSU app now, i get an error saying:- "There is no SU binary installed, and SuperSU cannot install it"
Some help would be appreciated. Screenshots attached.

I've managed to fix the issue. I just re-flashed the CM-Update file (located in the pone's internal memory), and got some ROOT access prompt while trying to open Thunderzap again. Thereafter, I installed SuperSU from the Playstore and got my binary updated through it. :good:

Root works but no root application

Hello,
After upgrade my nexus 7 from 4.4.4 to 5.1.1 with nexus toolkit all application needs root works perfect, but no root app (e.g. SuperSU or Superuser) appears in menu. I installed SuperSu from TWRP recovery but Application list in SuperSu is empty and all apps needs root works without showing message to allow or deny root access.
How can fix it?

After re-flashing system.img an new installation of SuperSU from TWRP, the problem solved!

Of course you lost root and TWRP because a update.zip contains also recovery and other things(vendor, custom, etc.) and by flashing it the stock recovery will overwrite your TWRP and the new system will delete your root access.
And NEVER install KingRoot on this device! It will mess a lot of things(SuperSU and Magisk work)
You will need to flash TWRP again in order to have root because both supersu and magisk need to be flashed through TWRP(because they are .zip files, at least a part of the root, you will need to install the magisk app to have full root)
SuperSU root just needs to be flashed, just magisk needs an app to be installed after .zip flash.
